I thought it would be specific with tools here, I have created some
dummy bl31.elf if BL31 is not set but the
arch/arm/mach-rockchip/make_fit_atf.py can't make the build. on the
other hand I have compiled main(){} and created bl31.elf it is
succeeding.

But for sunxi the build is going as normal by setting /dev/null if BL31 unset.

[ -z "$BL31" ] && BL31="bl31.bin"

if [ ! -f $BL31 ]; then
        echo "WARNING: BL31 file $BL31 NOT found, resulting binary is
non-functional" >&2
        echo "Please read the section on ARM Trusted Firmware (ATF) in
board/sunxi/README.sunxi64" >&2
        BL31=/dev/null
        echo $BL31
fi
